About the Raspberry pi adapter PCB

Raspberry pi adapter is an open source Raspberry Pi PCB design by NightLaneOrg, published on GitHub under the GPL-3.0 license. It is a 2-layer board measuring 65 × 56 mm, with 11 components from 7 distinct parts.

Its main chip is the Raspberry_Pi_4, from the Raspberry Pi family. Other key parts include the SN74AXC4T245PW and TLV70018_SOT23-5. By type, the board carries 4 capacitors, 3 resistors, 2 ICs and 2 connectors.

It belongs with the rf & radio and audio designs in this gallery.

From the project

Si468x-based DAB/FM receiver module (M.2 E-Key) with open hardware and Linux integration.

Open-source DAB/FM receiver module based on the Silicon Labs / Skyworks Si468x series.

This project provides hardware, software, and documentation to integrate a modern digital radio receiver into automotive and embedded Linux systems.

The Si468x is a highly integrated broadcast receiver supporting:

- DAB / DAB+ - FM (RDS) - Digital audio output via I2S - Control via SPI / I2C

Raspberry pi adapter: common questions

What microcontroller does the Raspberry pi adapter use?

The Raspberry pi adapter is built around the Raspberry_Pi_4, from the Raspberry Pi family.

How big is the Raspberry pi adapter PCB?

The Raspberry pi adapter measures 65 × 56 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Raspberry pi adapter?

11 components, from 7 distinct parts. The full bill of materials is listed on this page.

Where can I download the Raspberry pi adapter design files?

From the NightLaneOrg/nr-si468x-module repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Raspberry pi adapter design in my own project?

Yes, under the terms of its GPL-3.0 license, which NightLaneOrg chose for the repository.

Can I test firmware for the Raspberry pi adapter without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug Raspberry Pi firmware against it before you order a PCB.
